Which type of injury occurs when a joint is pulled or twisted causing torn ligaments?
A sprain is caused by an injury that stresses a joint and overstretches or even ruptures supporting ligaments. This can happen from a fall, twist, or blow to the body, In a mild sprain, a ligament is stretched, but the joint remains stable and is not loosened.
What are the steps of smooth muscle contraction?
Steps involved in smooth muscle cell contraction:
- Depolarization of membrane or hormone/neurotransmitter activation.
- L-type voltage-gated calcium channels open.
- Calcium-induced calcium release from the SR.
- Increased intracellular calcium.
- Calmodulin binds calcium.
- Myosin light chain kinase activation.
Which muscle cells have the greatest ability to regenerate?
Smooth cells have the greatest capacity to regenerate of all the muscle cell types. The smooth muscle cells themselves retain the ability to divide, and can increase in number this way.
What are the 4 layers of the GI tract?
All segments of the GI tract are divided into four layers: the mucosa (epithelium, lamina propria, and muscular mucosae), the submucosa, the muscularis propria (inner circular muscle layer, intermuscular space, and outer longitudinal muscle layer), and the serosa (Figure 1).

What are the 3 types of muscle strain?
Muscle strains can be categorized into three grades, based on severity:
- Grade 1: Mild damage to individual muscle fibers (less than 5% of fibers) that causes minimal loss of strength and motion.
- Grade 2: More extensive damage with more muscle fibers involved. …
- Grade 3: Complete rupture of a muscle or tendon.
Which joints are most often sprained?
Sprains occur when a ligament, the connective tissue that holds our joints together, is stretched or torn. Sprains are usually the result of an acute injury, such as a sudden twist of the limb or a fall onto your outstretched arm. Sprains most often occur in the ankles, knees, and wrists.
